After defeating Themis again, Mario and the others return home via Rosalina's Comet Observatory when they bump into a lighthouse. It turns out to be the Cosmic Lighthouse, home to Cosmetta, Rosalina's sister who hasn't seen her in years. They two reunite and then realizes that Cosmetta is about to destroy a planet with a black hole. Rosalina stops Cosmetta but the planet she was just about to destroy breaks apart to reveal a villainous creature named Khrysalis and the Elemental Stars, a villain who blasts the observatory and lighthouse away. Cosmetta shoots at Khrysalis with a black hole gun. Rosalina realizes that the black hole merely relocated Khrysalis into a alternate dimension.
In this alternate dimension, Khrysalis is able to control The Comet Observatory, The Cosmic Lighthouse, Peach's Castle, and Daisy's Kingdom as they soon realize. Khrysalis kidnaps the Toads, the Lumas, Princess Peach, and Princess Daisy with representations of Themis, Bowser, Tatanga, and Slanito. The Elemental Stars were scattered due to Cosmetta's attack and Rosalina realizes that they need to use the Elemental Stars to defeat Khrysalis. Mario, Luigi, Rosalina, and Cosmetta head to find the Elemental Stars to fight Khrysalis and defeat her once and for all.
